Machine Key Stock
Cut this square or rectangular key stock to length to create a straight machine key. Straight keys are the most common type of key. Machine keys are often the same material and as hard or harder than the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.
Steel key stock is an economical choice with good strength. 8630 alloy steel key stock meets ANSI B17.1 class 2 specifications for dimensions and tolerances.
Stainless steel key stock is more corrosion resistant than steel key stock. 18-8 stainless steel key stock offers a balance of strength and corrosion resistance. It may be mildly magnetic. 316 stainless steel key stock has the best corrosion resistance of our stainless steel key stock and may be mildly magnetic. 416 stainless steel key stock is stronger than other stainless key stock, and can be heat treated for extra strength. It's corrosion resistant and magnetic.
Brass key stock is corrosion resistant and nonmagnetic. Brass is softer than other metals, so it's often used for shear keys.
Aluminum key stock is one-third the weight of steel key stock, but not as strong. It resists corrosion and is nonmagnetic.
Acetal plastic and nylon 6/6 plastic key stock are slippery and wear resistant. Acetal resists swelling when exposed to moisture.
PEEK plastic key stock resists chemicals, moisture, and high temperatures. It meets MIL-P-46183 Type 1 specifications for nonreinforced plastic.
Slightly larger than the size listed in the table, oversized stock fits tightly in a keyway. Press it into place for use in high-torque applications or to replace a key in a worn keyway. Slightly smaller than the size listed in the table, undersized stock is the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use it when parts need to be taken apart frequently, such as for maintenance or prototyping.
Key stock that meets DIN 6880 specifications conforms to DIN standards for undersized keys.

Rounded Machine Keys
When installed, these keys fill oval keyways completely, reducing stress on the key and shaft. Using them in a closed keyway keeps them from sliding along the shaft axis. The rounded ends make it easy to slide gears, hubs, and other components into place. Also known as feather keys. Machine keys are often the same material and as hard or harder than the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.
316 stainless steel keys have excellent corrosion resistance, but aren't as strong as steel keys. They may be mildly magnetic. Slightly smaller than the size listed in the table, undersized keys are the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use them when parts need to be taken apart frequently, such as for maintenance or prototyping.
Metric keys conform to DIN 6885 standards.
